It's more about capturing something that someone does not want to be seen and later traceable back to you because you didn't know about your phone embedding data into pictures. Say for example, you caught me killing a puppy with your camera phone. I'm your neighbour so you post the picture online with a hint to location via an anonymous account through many proxies. There's newspaper frontpage outrage and I'm outraged. I investigate and look at the picture file. Lo and behold, I recognise the camera make as yours and know who it is. So it's not only police that you want to protect yourself from. Disclaimer: I like puppies though :(
